The Usoi Dam is a natural landslide dam along the Murghab River in Tajikistan. At 567 metres (1,860 ft) high, it is the tallest dam in the world, either natural or man-made. The dam was created on 18 February 1911, when the 7.4-M s Sarez earthquake caused a massive landslide that blocked the flow of the river. [1]
Landslides can interfere with denudation measurements in mountainous regions, especially the Himalayas. [31] The two main problems with dating methods are uncertainties in the measurements, both with equipment used and with assumptions made during measurement; and the relationship between the measured ages and histories of the markers.

Rapid changes in the groundwater level along a slope can also trigger landslides. This is often the case where a slope is adjacent to a water body or a river. When the water level adjacent to the slope falls rapidly the groundwater level frequently cannot dissipate quickly enough, leaving an artificially high water table.
This type of measure is used in cases of smaller landslides. The effectiveness of micropiles is linked to the insertion of micropiles over the entire landslide area. In the case of rotational landslides in soft clay, the piles contribute to increasing the resisting moment by friction on the upper part of the pile shaft found in the landslide.
A large landslide entered Sullorsuaq Strait, generating a megatsunami which struck Alluttoq Island, where it had a run-up height of 45 to 70 metres (148 to 230 ft). [15] ~2800 BCE Zion Canyon, Utah, US: 0.286 km 3: Landslide created the currently level floor of Zion Canyon inside Zion National Park. [21] ~1920 BCE Jishi Gorge, Qinghai Province ...
Real-life landslide on a slope. Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement; the opposite condition is called slope instability or slope failure. The stability condition of slopes is a subject of study and research in soil mechanics, geotechnical engineering, and engineering geology.
Debris flows have volumetric sediment concentrations exceeding about 40 to 50%, and the remainder of a flow's volume consists of water. By definition, “debris” includes sediment grains with diverse shapes and sizes, commonly ranging from microscopic clay particles to great boulders.
The first evidence of people in Lochearnhead comes from Mesolithic arrowheads found in Glen Ogle by former local policeman Tom Gibbon, and his son Donald. [2] A settled population is in evidence in the Neolithic period, from a burial chamber at Edinchip, [3] and from the cup-marked stones which lie between the Kendrum Burn and the Craggan Road, [4] in what is known locally as the Druid Field.
